Abstract
A method and apparatus for releasing remaining subscriber activities through the use of a service termination command. A home public land mobile network (HPLMN) is informed of remaining activities by visited PLMNs (VPLMN) and interrogating PLMNs (IPLMN). The HPLMN sends a timer to the VPLMNs and IPLMNs in a MAP operation. If upon expiration of the timer the subscriber has remaining activities in the node, then the node sends an alert to the HPLMN. The timer may be based upon a fraud risk of the PLMN and/or of the fraud risk of the subscriber. Accordingly, the HPLMN waits for an alert from a particular node before sending a service termination to the node.
Claims64
A method for monitoring a subscriber's activities in a radiocommunication system comprising the steps of:
- sending a first timer value from a home location register (HLR) with a message to a first node associated with said subscriber's activities;
- waiting, in said first node associated with said subscriber's activities, until a first time period based on said first timer value has elapsed;
- and
- reporting activities in said first node associated with said subscriber to the HLR upon expiration of said timer value.
In a GSM radiocommunication system, a method for tracking subscriber activities when a subscriber is no longer within a visiting location register's (VLR's) zone of responsibility, comprising the steps of:
- sending a timer along with a message to the VLR,
- wherein, upon expiration of the timer the VLR sends an IST alert to an HLR associated with said subscriber if there are any activities associated with said subscriber in said VLR.
An apparatus for monitoring a subscriber's activities in a radiocommunication system comprising:
- means for sending a first timer value from a home location register (HLR) with a message to a first node associated with said subscriber's activities;
- means for waiting, in said first node associated with said subscriber's activities, until a first time period based on said first timer value has elapsed;
- and
- means for reporting activities in said first node associated with said subscriber to the HLR upon expiration of said first timer value.
A method for monitoring a subscriber's call related events in a radiocommunication system comprising the steps of:
- sending a first timer value from a home location register (HLR) with a message to a first node in which the subscriber's call related events are pending;
- waiting in the first node until a first time period based on the first timer value has elapsed;
- and
- reporting the subscriber's call related events in the first node to the HLR upon expiration of the timer value.
In a GSM radiocommunication system, a method for tracking a subscriber's call related events when the subscriber is no longer within a visiting location register's (VLR's) zone of responsibility, comprising the steps of:
- sending a timer value along with a message to the VLR;
- and
- sending from the VLR an IST alert to an home location register (HLR) of the subscriber upon expiration of the timer value if there are any subscriber's call related events pending in the VLR.
An apparatus for monitoring a subscriber's call related events in a radiocommunication system comprising:
- means for sending a first timer value from a home location register (HLR) with a message to a first node in which the subscriber's call related events remain pending;
- means for waiting in the first node until a first time period based on the first timer value has elapsed;
- and
- means for reporting the call related events in the first node to the HLR upon expiration of the first timer value.
A method for preventing fraudulent activity in a radiocommunication system comprising the steps of:
- sending a timer value from a home location register (HLR) with a message to a first node in which a subscriber's call related events are pending, wherein the timer value is based upon a risk of fraudulent activity by the subscriber;
- waiting in the first node until a time period based on the timer value has elapsed;
- and
- reporting the subscriber's call related events in the first node to the HLR upon expiration of the time period.
